GPR Exhaust - poor man's Akro?
« on: July 21, 2020, 05:46:23 pm »
Fitted a GPR Titanium exhaust to the K1300 GT yesterday.

I'm chuffed with it - a much nicer sound but not droning and booming and likely to be a problem on a long trip.

Just what I wanted and much cheaper than an Akro.

Very happy. ;D

Great exhaust the GRP, I have used them for some years now with no problems, good price and excellent quality not like most of the after market exhaust manufacturers that have been ripping bikers off for years, my last one for the 1200GS cost only £260.

I fitted a GPR Furore in ceramic black aluminium to the wee Honda last week. I'll have to stop calling it wee now because it doesn't go weeeeee anymore but it is still only a 250.

I was umming and ahhing between the Italian GPR and Bitish made Delkevic.

The GPR was £289 for the silencer only whereas I could have had a complete stainless system from Delkevic for £250. In the end, the Italian won out but they had none in stock so mine was made just for me and arrived with my name on the swingtag which was a nice touch. Pity it took 3 weeks to walk it up from Italy but the results were excellent.

No Cat compared to two, three-way cats in the OEM one and according to my kitchen scales the silencer weighed in at 2kgs and the link pipe and fittings took it to 2.5 whereas the stock boat-anchor was all of 5.2kgs and the Honda wears it much higher up than the K.

Being a straight through, free-flow jobbie, the GPR also freed up the breathing on the Honda and it is much livelier now than it was before.

As you said, quite a fruity note and much sportier to boot.

Only thing i'm not keen on with these is the hanger. Am looking at them for the GS now though, and even with the hanger issue, can't complain at ~£280 for that Furore! I'm sure I could make something fancy for the hanger... or forget about it and just ride.

Damn it I'm supposed to be saving money!

WTF?

A hanger is in a hangar! What sort of hamburger d'you want.

If you want a 'dedicated' hanger, pay the man and get an Akra.

If you want a GPR or a Delkovic quit yer bellyachin and get a silencer wiv a strap and a hanger...

£1,000 for a dedicated hanger...

£250 for a strap...

Get over y'sel man  8)

I didn't hear this moanin wiv yer SC Projek, innit  :)

Wouldn't mind a hamburger though please.

Watching properly now!

2:28 your sound has gone tin-tinny-tin-tin by the way. Gosh, they wrap the bits up nice don't they! Sound back to normal at 4:00 :)

Aah so the rubber bit is just to prevent scratching the can then. Probably obvious but your video makes it easy to see.

Looks lovely on the bike, much neater. Jolly good! Post pay-day I shall order one. Then I need to see about those servo eliminator things for the quiet-flap.

Don't worry, this thing has about 8km of catalytic honeycomb goodness in its intestines so it'll never be half as loud as the K with SC-Project :). And by half as loud I don't mean literally 1dB less :P

I've just had a look at these on ebay, £280 for  GPR Furore Nero, which looks very nice, however I really want one now for their write up

"GPR are hand made in their own Milan based factory. Do not let the very reasonable price put you off. If you feel you would like to pay twice as much for something you cannot pronounce and is on every other bike then this is not for you. If however you would like a good quality exhaust at a reasonable price supplied by a trusted UK seller on the end of a phone and also show some individualism, then this is very much for you"

Viva la difference. 

Love it  :)

Experimenting with new microphone and new camera (Canon M50). I'm not the best with these things, but I dare say I'll get the hang of it in the end :-[.

The nice gent at Moto-legends where I got the exhaust has pointed out a few things:

1. The bags are apparently for you to put your crash hat and old exhaust in.
2. The end of the exhaust is not plastic but an aluminium alloy called ergal, painted in ceramic paint.
3. There is a removable db killer.

I have modified the video once more.

https://youtu.be/HbhRb9ipxCg


Price of the exhaust was £379.

Here's their full range. I believe they are still doing free delivery at the moment.
